International Association of Meteorology and Atmospheric Sciences (IAMAS)

At the First IUGG General Assembly (Rome, 1922), the Section de Météorologie became one of the constituent sections of the Union. At the IV IUGG General Assembly (Stockholm, 1930) it became the International Association of Meteorology. It took the name of International Association of Meteorology and Atmospheric Physics at the XI IUGG General Assembly (Toronto, 1957), which later became the International Association of Meteorology and Atmospheric Sciences, (Association Internationale de Météorologie et des Sciences Atmosphériques) in 1993.

IAMAS promotes research in all atmospheric sciences, especially programmes requiring international co-operation. IAMAS leads the Alliance for Capacity Transfer (ACT) - a joint activity of IUGG, the World Meteorological Organisation (WMO), and the U.S. University Corporation for Atmospheric Research (UCAR). IAMAS is composed of 10 International Commissions on the following topics:
